Getting Around 170rwkw Out Of Rb20det

Thinking I might just get one of those ARC SMIC's. There's a used one on eBay for around $400.

As for dump pipe, I'm looking at the justjap dump and front mild steel one. I figure if I get that dump pipe with ARC SMIC, should be more than enough to get around 160rwkw with high flow cat, catback exhaust, fuel pump and sports intake filter.

Will try to avoid ECU and Boost Controller, unless I need to.

I had a boost drop issue with the std rb20det turbo.

I was making 152rwkw on 12.5psi and when dialed in 1bar it made 155rwkw. Problem was boost was dropping from 1 bar to just under 13psi.

Fitted up the ebc, set it in auto mode, learnt the boost curve and it held 1bar to redline making 164rwkw. This was almost 4years ago now. :P

I had mine dyno'd at 173KW (229HP). RB20DET

Just the usual bolt ons + R33 turbo and old Profec EBC which held 0.8bar (12psi) all the way.

The old owner had it dyno'd at 188KW at 1Bar a while ago, but I'm not too keen to run it that high.

Which ECU are you using? I've got a fuel pump and front mount intercooler in mind, it's just a matter of arranging an ECU. I've heard mixed things about Dr Drift.

Thanks,

Adrian.

I went with an EMS 8860 ecu. It set me back $1450 plus tune.

I was running std actuator pressure on the rb20det turbo to make 176rwkw. I suspect my dump pipe is crap as I've always had an issue with boost drop.

I was running 12psi by ~2000rpm which would then tail off to 9psi by peak power.

Now looking at the power curve it was most definitely starting to valve float a little over 4000rpm, now that I've tried running more boost through the new turbo it really pops its ugly head up and pumps up the lifters. :(

But no it never died... Its got within spec shaft movement and feels better than the vg30 I slapped on there. :P

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
